TI TPS84621 6A DC-DC总体电源解决方案

TI 公司的TPS84621RUQ是容易使用的综合电源解决方案,集成了6A的DC/DC转换器和功率MOSFET,电感和无源元件.总体电源解决方案仅有三个外接元件,不需要回路补偿和磁性部分处理.效率大于90%,9×15×2.8 mm BQFN封装,热阻仅为13°C/W,输入电压可低至1.6V,可调开关频率250 kHz 到780 kHz,在85度C环境温度时可提供6A的额定电流,可用在宽带和通信基础设备,自动化测试和医疗设备,DSP和FPGA点负载电源,高密度分布电源系统,紧凑的PCI / PCI Express / PXI Express.本文介绍了TPS84621主要特性,功能框图,典型应用电路以及TPS84621EVM-692 6A评估模块主要特性和指标,电路图,材料清单和PCB布局图.

The TPS84621RUQ is an easy-to-use integrated power solution that combines a 6-A DC/DC converter with power MOSFETs, an inductor, and passives into a low profile, BQFN package. This total power solution allows as few as 3 external components and eliminates the loop compensation and magnetics part selection process.

The 9×15×2.8 mm BQFN package is easy to solder onto a printed circuit board and allows a compact point-of-load design with greater than 90% efficiency and excellent power dissipation with a thermal impedance of 13°C/W junction to ambient. The device delivers the full 6-A rated output current at 85°C ambient temperature without airflow.

The TPS84621 offers the flexibility and the feature-set of a discrete point-of-load design and is ideal for powering performance DSPs and FPGAs.
